Quizplus · Accepted Answer

Statement I is incorrect because a compound microscope has two lenses, the objective lens and the eyepiece lens. Statement II is correct as the magnification produced by the objective lens is dependent on its focal length and the distance between the objective lens and the specimen. Statement III is incorrect as the total magnification is the product of the magnification produced by the objective lens and the eyepiece lens. Statement IV is also incorrect as the aperture is the opening in the iris diaphragm of the microscope, which controls the amount of light passing through the specimen, not the magnification. Therefore, only statements II and III are correct.
